Buying one ( 1 ) propeller KIT measuring 5.5" tip to tip.  This 4 blade  wooden propeller comes UN assembled from genuine mahogany  . Your kit comes with a bushing and a #6 x 1.5" long brass screw for installation and is what we  use on our planes. The hole will need to be enlarged to 1/4" to accept the bushing. We recommend drilling the hole AFTER the propeller has been sanded .

*** Rotation of the propeller turns so the screw will not back out *******
